Hey guys, So, I just got my network reconfigured and Intervlan Routing set up with 6 different VLANs. The switch has DHCP enabled and configured and WAS issuing IP addresses to the devices. What SEEMS to be happening is when the lease expires for a device and tries to renew, the switch fails...

What would the X’s and Y’s be on the ACL? I’ve never done an ACL.

That’s what cisco’s Website said to do. Otherwise, Port 23 would have to be trunked and Router-on-a-Stick configured on the Router G0/1 Port with trunking enabled on the router as well. So, instead of doing all that crap, I just did the fast easy way that Cisco recommended on their site. Lol...

Port 23 has the IP address in the 10.0.0.0 range and it sees the router with the routes configured and all hosts on all vlans have Internet Access and are pulling IPs from the DHCP Servers on the switch.

Okay, after hours and hours and hours of fighting, I got network connectivity back with internet. I think i finally got intervlan routing up and running with DHCP coming from the switch and not the router. However, I have noticed that when host devices connect to the network, the network...

I’m in deep doodoo. I am trying to implement the inter VLAN routing on the L3 switch and completely crashed my entire network. Nothing is communicating and I have no internet. Switch can ping the router still. But nothing else can work.

It’s “into range f0/1-3” to erect a range. Lol. Now, if I do seitchport access and assign the VLAN, will that disable the interVlan routing that was just enabled since enabling and configuring it has me turn it off? That’s why I’m confused on how this is gonna work. I’m gonna try it...

I am still confused though. Once I enable IP Routing on the S1, how would I assign ports on S1 to specific VLANs?

If I am understanding correctly, The router would be the WAN Access (Gateway), S1 would be set to Layer 3 Routing between VLANs, and S2 would just be trunked to S1 and each port assigned their specific VLAN access (remaining Layer 2)??

I would rather the router or the S1 (Main Switch) assign all IP Addresses to the end devices. My servers have enough to do as it is. LOL. So would I use the Switch to do the IP Assignments (DHCP Server) or continue using the router? Which would be easier on the network itself and help increase...

My router config that I posted is the current configuration with Firewall ACLs. Now that I am redoing my entire network with VLANs and maybe InterVLAN Routing, the Router Config will most likely change. I still need to have DHCP Servers/Pools for each VLAN/Subnet. WOuld I do the DHCP Pools...

Here is the configuration of Switch2 so far. Its NOT complete. I just want to make sure I am on the right track with configuring the switch2 to access Switch1 and have Ports 1-4 access the correct VLANs. Any insight, advice? S2#show config Using 1708 out of 524288 bytes ! ! Last...

This is my current configuration of my router. WOuld it be easier to reset to default and start fresh and new? R1#show config Using 11154 out of 262136 bytes ! ! Last configuration change at 00:14:59 UTC Fri Mar 24 2017 by administrator ! NVRAM config last updated at 00:15:03 UTC Fri Mar 24...

I’m trying. Problem is, the entire time I’m “experimenting”, trying to get this right and working, my entire network is down. So, down time is waaaay too much. I’ll try to write up the config commands and post. Hopefully it actually freaking works.

Here is my new design with subnets and different VLANs that do not use VLAN1. Now all I gotta do is figure out how to correctly program this and enable the Layer 3 to easy the load off the actual router. Cisco 2911 Gigabit Router Cisco WS-3750E Gigabit Layer 2/3 Switch (S1) Cisco ws-c3560...
